NITED STATES WILLIAM H. GRAHAM, OF

BLENHEIM, SOUTH CAROLINA.

BOX- ALL-SECURING MEANS.

Application filed January 4, 1924-. Serial No. 684,404.

To aZZ whom it may concern:

Be it known that I, lVILLrAM H. GRAHAM, citizen of the United States, residing at Blenheim, in the county of Marlboro and State of South Carolina, have invented certain new and useful Improvements in Box- VVall-Securing Means, of which the following is a specification.

This invention relates to the general art of boxes and has more particular reference to means in the form of fasteners whereby the ditlerent walls of the box may be rigidly secured together without the necessity of nailing the same, the nature of this present fastening means being such as to allow the box tobe readily knocked down for shipment purposes.

The primary object of the invention resides in the provision of fastening means for the walls of boxes that will maintain the same in a set up position extremely more rigidly than is now possible by the employment of nails, the nature of the fastening means used for carrying out this invention being such as to permit of their manufavture and use at extremely small cost.

\Vith the foregoing and other objects in view as the nature of the invention will be better understood, the same comprises the novel form, combination and arrangement of parts, hereinafter more fully described, shown in the accompanying drawings and claims.

In the drawings wherein like reference characters indicate corresponding parts throughout the different views,

Figure 1 is a side elevational view of one corner of a box to which is applied one of the corner fastenings constructed in accordance with the present invention,

Figure 2 is an elevational view of the corner of the box taken at right angles to Figure l, for disclosing in and elevation, said corner fastenings,

Figure 3 is a top plan View thereof,

Figure at is a fragmentary side elevational view of the box equipped with a form of fastener constructed in accordance with the present invention whereby the top of the box is firmly securedin position thereon,

Figure 5 is a detail vertical cross section taken substantially upon the line 5-5 of Figure 4,

Figure 6 is a plan View of the sheet metal blank from which the major plate element of the corner fastening is formed,

Figure 7 is a similar view of one of the sheet metal blanks from which certain other members of this corner fastening is formed, and

Figure 8 is a still further similar view of the sheet metal blank from which the main plate securing bracket of the corner fastening is formed.

Now having particular reference to the drawings wherein there is shown fragmentarily a box, the walls of which are rigidly joined together through the medium of the present fastening means, 5 designates the side walls of the box and ('3 the cover wall or lid thereof. The present type of box includes wooden strips 7 applied to the marginal edges of said side walls and similar wooden strips 8 applied to the marginal edges of said top wall or lid 6.

Applied to the eight corners of the box are corner fastenings constructed in accordance with the present invention. Each of these corner fastenings comprises a main substantially rectangular shaped sheet metal plate 9 that has two of its diametrically opposed corners cut out as clearly shown in the plan view, Figure 6. This blank plate 9 is applied to the corners of the box as clearly shown in Figure 1, after which the upper and outer edge are bent inwardly upon the fold lines 10 and 11 for providing flanges 12 and 13, respectively, for close engagement with the adjacent strip 8 of the top of lid 6 as well as the adjacent strip 7 of the side wall 5. i

The flanges or ears 12 and 13 formed by bending the said edges of the rectangular shaped plate 9, over upon the fold lines 10 and 11, respectively, are provided at certain points with oblong slots 12 and 13, respectively, and previous to the applica tion of this element of the fastening means to the box, metal strips 14; and 15 are placed upon the right angularly extending wooden strips 8 and 7 of the top and respective sides thereof. It will be noticed that these strips 14; and 15, extend at direct right angles with respect to the flanges of the metal plate 9 and terminate at their outer ends beneath said flanges as clearly shown in the dotted lines of Figures 2 and 3.

These metal strips are parts of blanks of a formation clearly shown in Figure 7. The rear end of the inner edge of these blanks are bent inwardly at right angles upon the fold line 16 for engagement over the inner edge of the respective wooden strips. The front ends of the inner edges of these blanks are severed from the strip portions l i thereof, as at 17 whereby these portions of the inner edges of said blanks may be bent at right angles to the rear ends thereof so as to be secured at 18 to the inner edges of the right angularly extending wooden strips 7 or S as the case may be.

The outer corners of the front ends of the metal strip portions 14 0f the blanks are formed with cut out portions 18. the material forming the inner edges thereof being so engagement within the before mentioned slots l2 and 13 of the flanges 12 and 13 respectively of the corner plates. it the eight corners of the box between the adja' cent edges of the wooden strips 7 of the side walls 5 of the box and directly beneath the innermost notched corner of the plate members 9 of the corner "astei'ling means are U-shaped members 19 formed from sheet metal blanks ot the type disclosed in Figure 8. At said inner cut-out corners of the rectangular shaped plates 9 ot' the inner corner fastening means are tongues '20 that carry eye bolts 21, the threaded ends of which engage through openings in the elements 19, after which nuts 22 are threaded thereon, it being obvious from this construction that a highly novel and rigid form'o'f corner fastening for boxes is thereby produced.

Secured to the inner edge of each of the wooden strips 7 of the side wall of the box and at points substantially intermediate the ends thereof, U-shaped brackets 23 almost identical with the form of bracket before "described and designated by the reference character- 19. Positioned upon the sides of the box at-the outer edges of the same, are plates 2& of sheet metal that are formed at their upper ends with inwardly extending flanges 25 that engage over the wooden strips of the adjacent side walls of the box, the lower ends of these metal plates being also flanged inwardly as at 26 for engagement beneath the inner wooden strip as clearly shown in Figure 5, these flanges being formed with pendant ears or tongues 27 whereby said plates may be rigidly secured to thebrackets 23 through. the eye bolt and nut connections 28.

From the foregoing it will at once be apparent .to those skilled in the art, that I have provided a highlynovel and etticient form of securing means for the walls of boxes, and even though I have herein set forth the most practical embodiments of bent as to provide hooks 19 foredge of the adj acent the invention with which I am at this time adapted for positioning upon said strips,

flanges formed at the outer ends of the plates for engagement over the strips of the 7 right angularly extended box walls, means for rigidly detachably securing the-plates in position, said means comprising bracket members secured to the inner edges of the strips towhich said plates are applied. and

adjustable connections between the brackets and plates.

2. A knock-down box comprising a plurality of walls arranged in abutting rela tion, and means for maintaining .the walls in assembled position, said meansembodying a plate provided along one edge with a laterally directed flange to hook over one wall of the box, said plate being further provided with an apertured-ear, an eyebolt carried by said ear, and an anchoring bracket provided withan opening through which the threaded nut carrying end of the bolt is adapted to pass.

8. A box fastening device comprising a cornice plate provided with a pair of laterally directed fianges to hook over right angularly disposed walls of the box, said plate being provided at a point opposite the flanges with an apertured ear, an eye bolt, the eye of which is attached to the ear, an anchoring bracket adapted to be attached to one of the end walls of the box, said bracket being provided with an opening to accommodate the threaded nut carrying end of said bolt.

4-. A box fastening comprising substantially rectangular cornice plates provided on two of its edges with laterally directed flanges, said flanges being provided with openings, the plates being formed at diametrically opposite corners with apertured wiLniAM nasnanan.
